To (tZZ whom it may concern:

Be it known that '1, WILLIAM B. LANTZ, a citizen of the United States, residing at Gloucester, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Rope-Hauling Machines; and I do hereby declare the follow ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in rope-hauling machines, and has more particularly to do with that class of machines that are employed for hauling the purse-lines of seines and for that purpose are mounted in a boat or like floating body.

The invention consists in mounting in a suitable framework groovedwheels for engaging the rope and operating gearing mounted in the said frame between the grooved wheels, the said gearing comprising gearwheels of different diameters secured to the shaft of the grooved wheels and actuating gear-wheels of different diameters adapted to engage the gear-wheels upon the shaft of the grooved wheels and adapted to slip back and forth in the frame for engaging one or the other of said gear-wheels for changing the power and speed of the apparatus at will, means being used upon said gear-wheelstolimit said slip movement to certain predetermined points upon the gear-Wheels.

It also consists in certain other constructions, combinations, and arrangements of parts, as will be hereinafter more particularly set forth and claimed. v

In the accompanying drawings, Figure 1 is a side elevation of my improved rope-hauling machine as mounted upon the seat of a boat,- the boat being shown in cross-section. Fig. 2 is a detail sectional view of the boat; taken transversely through the seat thereof, the machine being turned down from the top of the seat out of the way ofthe rowers. Fig. 3

is a top plan view of therope-hauling machine, showing the arrangement of the gearing for operating the same. Fig. 4 is a side elevation of one of therope-hauling groovedwheels, showing a ratchet formed on the side thereof. Fig. 5 is a side elevation of one of the gearwheels, showing some of the teeth thereof gear-wheel 12 closed at the side to prevent the slip movement of the gearing except at certain intervals. Fig. 6 is a detail view showing the manner of connecting the handles to a powershaft of the device; and Fig. 7 is a detail sectional view through the shaft of the ropehauling wheels, showing. the construction of the gear-wheels secured thereon.

A in the drawings represents the improved rope-hauling machine. B represents the gearing thereof, 0 the'operating-handles, and D the seat of a boat.

The wheels a a having grooves in their peripheries for engaging the ropes to be hauled, are mounted upon the ends of a cross-shaft a, carried by the frame of the machine. Mounted upon the shaft a between the grooved wheelsaa are gear-wheels I) Z). The gear-wheel b is preferably provided with an elongated hub, as at 12 and the hub of the gear-wheel b is preferably secured rigidly upon the said hub 6 the proper space being allowed between thesaid gear-wheels Z) I). The hub b is'then securely keyed to the shaft a. In order to operate the said gear-wheels, a slip-gearing is mounted-in the frame, so as to engage the said gear-wheels. This gearing consists of gears b b, which are mounted upon a second shaft b carried in suitable bearings upon the frame. These gear-wheels b b are preferably made in a single casting, the gears 6 being formed upon the side of the These gear-wheels are keyed to the shaft Z2 so as to turn therewith. These gear-wheels b lib b may be of any desired size, but they are so proportioned as that when the gear-wheelb is moved opposite the gear-wheel Z) it will mesh therewith, and also so that when the gear-wheel Z2 is moved opposite the gear-wheel b it will also mesh with it. The shaft 1) is free to move longitudinally in its bearings a sufficient distance to permit of this change of gearing. Handles of any desired form may be attached to theends of the shaft 7) for rotating the'same; but I profor to use handles attached in an-imp'roved manner. Upon the ends of the shaft'h are keyed handle-attaching devices or pieces 0 c. The pieces 0 c are provided with sockets to receive the ends of the said shaft 19 to which they are keyed. Set-screws, as c, are also employed to lock the said pieces upon the end of the said shaft. Said pieces are further provided with sockets or apertures extending through the same, as at 0 which are adapted to receive the ends of operating-handles C O. The sockets c are preferably rectangular in shape and the ends of the handles C C, which tached from the shaft, and there is no danger of them slipping with respect to the shaft or dropping out of engagement therewith during the operation of the machine.

I preferably place the gear-wheels Z) bat a distance apart which shall be a little greater thanthe width of either one of the gear-wheels b 12. It will be seen that in using this mechanism as a slip-gear when the gear-wheel b is moved laterally with respect to the gear-wheel Z) the teeth of the gear-wheel b will of necessity engage the teeth of the gear-wheel b before the teeth of the gear-wheel I) leave the teeth of the gear-wheel b. Now as thegearwheels are of dilferent sizes it will be apparent that the openings between the teeth of the wheels I) b will not all coincide and that there will only be certain points upon the peripheries of these wheels where the teeth and their intervening apertures will exactly coincide. The same fact is also true in regard to the wheels 13 b By making the gear-wheels of certain sizes with relation to each other and providing them with a certain number of teeth, the teeth being all formed on the same pitch, it can be readily ascertained at what points the teeth of the wheels will be exactly opposite each other. I have provided a means in connection with my device whereby the slip gearing can only be moved at points where the teeth of the gear-wheel will coincide, and this construction constitutes a very important feature of my invention. Upon the inner surfaces of the grooved wheel a ratchet teeth, as a are provided. These ratchet-teeth are made of sufficient width to be engaged upon their peripheries by a pawl or dog aipivotally mounted upon the frame of the machine. By placing the teeth of this ratchet a onlyin such places with relation to the gearing that the pawl a will only hold the said gearing at those points where the teeth of the gear-wheels coincide the result will follow that when the machine is held by the said pawl the slip-gearing will always be free to move and can be changed as desired. It will be evident that the ratchet a might beplaced on the wheel a or a ratchet might be placed upon both the grooved wheels without departing from the spirit of my invention. In

order to prevent the chance of slipping the gearing when the machine is not held by the pawl as, for instance, when no rope is being hauled at a place where the gearing will not After the handles 0 have been coincide-r1 further provide the gear-wheel b with side flanges, as at b, which close the spaces between some of the teeth of the gearwheel at one side. These closing-flanges are placed opposite the intervals between the teeth which will not coincide, so that the slipgearing cannot be moved laterally except at the points where the intervals between the teeth are left open, care being exercised to place these intervals of open teeth at the points where the teeth coincide. By these simple expedients I am enabled to use a slipgearing for my ropehauling machines which will not be subject to loss of motion in chang ing the gearing and which can also be built to occupy a much narrower space in the machine than that occupied bythe ordinary slipgearing used in other machines.

In using this machine for hauling purselines of seines the frame is provided with a suitable base portion adapted to be secured in place upon a seat D of any suitable boat. The frame is hinged atone edge to the seat, as at cl, and is adapted to be secured at the other end in any suitable manner, as by hasp and pin. It is preferably'hinged toward the forward end of the heat, so that it may be turned down into thebottom of the boat upon the forward side of the seat and thus be entirely out of the way of the rowers of the boat when the machine is not in use. The wheels a a have their grooves formed V-shaped in cross-section, so as to bite the rope and hold it firmly for pulling it in. The rollers, as d cl, are pivotally heldagainst the peripheries of the wheels a a at such a point as to keep the rope in contact with the greaterportion of the peripheries of the wheels a a In order to prevent the rope from sticking in the grooves beyond that point, fingers, as d (Z secured to the frame, extend into the grooves of the wheels to a in such a manner as to lift the rope out of the grooves.

Having now described my invention, what I claim as new,and desire to secure by Letters Patent, is-
